This MagCAD top bearing cover allows you to mount a compatible Enve IN-Route stem to your Specialized Tarmac SL8 bike.
The remodelled top bearing cover matches the profile of the OEM Specialized Tarmac SL8 bearing cover to the shape of the Enve IN-Route system, allowing for completely internal routed cabling on your Tarmac SL8.
This MagCAD top bearing cover is 6.7mm in height, the same as the OEM Specialized Tarmac SL8 top bearing cover. The Enve stem can be fitted directly on top for a "slammed" low stack height setup or fitted with Enve IN-Route spacers, not supplied, for a taller headset stack height.
